Supporters of Brazil’s former President Jair Bolsonaro have stormed the nation’s presidential palace and Congress in Brasilia in protest of the election.
According to witnesses, protesters have also invaded the ministries’ building and the Supreme Court.
Images on social media show thousands of people streaming up the steps of the National Congress building in the capital city.
Most of the protesters appear to be patriots, draped in the yellow and green of the Brazil flag.
It is understood the supporters broke through a blockade set up by security forces and invaded the ministries building and Congress.
Protesters also surrounded the Planalto Palace, according to Reuters, and have now entered the Supreme Court.
Local media estimate that about 3,000 people are involved.
Brazil’s recently sworn-in President Luiz Inacio Lula da Silva is currently in Sao Paulo state, on an official trip.
Those who targeted Congress climbed on top of the building’s roof and broke the glass in its windows.
Protesters were seen on television smashing furniture inside the Supreme Court and Congress.
It is not immediately clear if they managed to break into the palace.
The incidents come after corrupt socialist Lula was sworn in on 1 January.
Supporters of Bolsonaro have been protesting against Lula’s contested election win since 30 October.
Protesters have been blocking roads, setting fire to vehicles, and gathering outside military buildings, asking the armed forces to intervene.
It comes just days after Bolsonaro moved out of the presidential palace.
